When coming to the in-situ-cast piles, they are having lengthy construction process that should be monitored through a well-organized quality controlling system. Driven cast in-situ piles are instrumented during the installation process to provide high quality records during the construction process. This type is highly used in all types of soil that includes weather rock soil and rock soil. Mainly piles are divided into two categories: in-situ-cast bored piles and driven piles. Cast-in situ piling: The bored cast-in-place piles are constructed by digging a hole in the ground then reinforcing it and filling the hole with concrete. Method of Installation of Bored Cast In-Suit Piles ( Fig. A robust testing schedule also demonstrates the high . (Mix shall be as per approved Mix Design, submitted separately) The slump of concrete shall vary between 150 mm to 180 mm for bored piles. The hydraulic rig will be centered over the designated pile location. The construction of bore cast in situ concrete pile consists of 4 primary phases 1.Pile boring, 2.Reinforcement cage lowering, 3.Flushing 4.Pile concreting. The casing may be left in position to form part of the pile, or withdrawn for reuse as the concrete is placed. Cast-in-Situ pile concreting shall conform to the relevant provisions of IS 2911 (Part 1/ Sec 2). The details of driven cast in-situ piles are shown. cast . Since the cast-in-situ piles is not subjected to handling or driving stresses, it is not necessary to reinforce the pile in ordinary cases or in places where the pile is completely submerged in the soil. This type of pile installation is used to replace soil removed by drilling rather than occupying the space of displaced soil as in driven piles. Depending on the situation and need various methods and machines can be used. 296 nos. The pile formed within the ground by excavating or boring a pile within it with or without the use of a temporary casing and subsequently filling it with plain or reinforced concrete. 2. 1 scope this standard covers the design of load bearing concrete bored cast-in-situ piles of diameter less than or equal to 1 500 mm which transmit the load of the structure to the rock through resistance developed either at the pile tip by end bearing or along the interface surface by pile rock Driven Precast concrete piles; Bored Precast concrete piles; What is Prestressed Concrete Pile. a) Cast-in-situ piles Specification 812 Bored Piles - 06/2471 Issued 19/10/2020 Document No: DXX#XXXX Page 5 of 20 Contract No: XXX/XX [Contract Name] SPECIFICATION 812 BORED PILES (WITHOUT PERMANENT CASING) GENERAL 812.01 SCOPE 1. Bored Piles are cast-in-place concrete piles, meaning the pile is cast on the construction site. Bearing capacity of bored cast-in-situ piles by post pressure grouting can be effectively improved through the grout pipes placed within the piles when concrete is 10-20 days old. .1 Method Statement: A method statement shall be submitted by the piling Sub-contractor for approval which shall include: i) Construction procedure. modified based on actual requirement.

The roads are small, traffic is heavy, there are restrictions on timings for movement of construction machinery and with all these limitations, the owners . The minimum amount of longitudinal reinforcement within a bored pile is defined within Table 3 . c. Reinforced concrete piles that are cast in situ have to comply with certain criteria to determine whether they are of sufficient size and depth for the actions they are required to resist. This type of pile is constructed in lengths varying from 6 to 12 m. The diameter of the pile varies from 40 to 60 cm at lop and the diameter at its base is slightly smaller, varying from 20 to 28 cm so as to give a uniform taper to the pile. The maximum spacing of the under-reamed pile should not normally exceed _____ a) 2 meters b) 2 meters c) 1.5 meters d) 30 centimeters Answer: b Clarification: The maximum spacing of the under-reamed pile should not normally exceed 2 m as to avoid heavy capping beams. The location of the pile will be marked using the total station with almost care. Bored pile is normally used for tall buildings and industrial complex in a depth of 50 - 55m. Concrete Strength of Bored Cast In-situ Pile. bored cast in situ piles. They were equally spaced in rows to give a maximum bearer span of 1350 mm, and rows were spaced 1.6-4.5 m apart (joist span). 7. They are used to accommodate higher loads, bypass underground impediments, and infiltrate the ground too hard to drill using a continuous flight auger, or to build stacks with a cut-off level below the platform level. Cast-in situ piling; Precast piling; 4) Types of pile foundations based on Installation . They can thus be tailored precisely to the partic- ular requirements of the building or ex- cavation. Replacement piles; Displacement piles; . Soil displacement piles are bored cast in-situ concrete piles constructed by advancing a displacement boring tool into the ground with a rotary drilling rig using both torque and crowd force. Bored cast-in-situ pile is formed within the ground Bored Cast In-situ Piles (BCIS) are most appropriate foundations for sandy soil and weak rock formations.
